The application of additive manufacturing is promising, and equipment manufacturing is the core of the industrial chain.

Additive manufacturing is a form of rapid prototyping technology and 3D printing (3DP), which belongs to the high-end manufacturing industry. Its basic principle is the principle of discrete stacking. Based on digital model files, it can be constructed by layer-by-layer printing using adhesive materials such as powdered metal or plastic. The additive manufacturing process mainly includes two processes of three-dimensional design and layer-by-layer printing. First, it is modeled by computer modeling software, and then the completed 3D model is divided into layer-by-layer sections to guide the printer to print layer by layer.

Compared with the traditional method of reducing material manufacturing, it has many advantages: 1. Shorten the time of manufacturing and improve efficiency; 2. Improve the utilization efficiency of raw materials; 3. Complete the realization of complex structures to improve product performance.

The additive manufacturing industry chain is mainly composed of five links, among which the upstream is raw materials, core hardware and auxiliary operation equipment, and the midstream of the industrial chain is the development and production of additive manufacturing equipment. The downstream demand involves aerospace, automobile, medical and other specifics. Application area. Overall, equipment development and manufacturers located in the middle of the industry chain are at the core, playing a decisive role in the development and application of manufacturing technology and the provision of product services.
